Doesn't run in background – Relax Sounds: White Noise App Review

This app goes silent once you activate another app, like an alarm clock. Also, the $2.99 premium upgrade is too expensive compared to competing ambient sound apps. I'm finding many of the ambient sound apps out there can't play in the background! An exception has been the Phase4 Mobile sound apps, like their Rain Sounds HQ and Rain Sounds Free. This particular app here has a nice selection of sounds and the interface is straightforward and practical. It works fine if you have a separate, tabletop alarm clock.
